Abstract Details

Purpose:

To assess the difference in pre and postoperative results of a modified Cat-Quest 9 questionnaire in patients who have undergone objective visual behavior assessment preoperatively using the Visual Behavior Monitor (VBM, Zurich, Switzerland).

Setting:

Five-site feasibility study in Ireland, Germany and Switzerland

Methods:

Patients presenting for cataract surgery or refractive lens exchange were randomly selected to take part. The VBM is a wearable that can track a patient’s lifestyle using a combination of sensors measuring distance, ambient light, head movement and position, resulting in an objective evaluation of patient’s activities. Patients were trained and fitted with the VBM and returned a week later to complete a modified Cat-Quest9 questionnaire to understand their expectations prior to surgery. One month after surgery, patients completed a post-operative version of the Cat-Quest 9. The results were compared with published e the Cat-Quest 9 studies.

Results:

118 patients completed the questionnaire pre-operatively. At the interim analysis, 67 patients had completed the 1-month follow-up visit. Pre-operatively, 82% of patients indicated that they had at least some difficulty with their vision in daily life, with 69% indicating they were very dissatisfied to rather dissatisfied with their vision. At the final post-operative visit, 79% reported that their vision matched or exceeded expectations. In comparison, a 2018 published study that used the Cat-Quest9 found that 88% of patients (N=153) were very dissatisfied to rather dissatisfied with their vision preoperatively. Postoperatively, 46% (N=80) were satisfied with their visual improvement.

Conclusions:

The comparison between Cat-Quest9 pre-operative and post-operative results suggests that the use of an objective assessment can help patients achieve visual results that exceed expectations in cataract and refractive lens exchange.
